Are you tuned in to others' mind? A cross-modal evaluation of affective theory of mind in people with Parkinson's disease.

Affective Theory of Mind (ToM) is the ability to understand other peoples' emotional states and feelings. Several studies showed impaired affective ToM abilities in people with Parkinson's disease (PD). However, most studies tested this ability by using single-stimulus modality tasks (visual cues). The aim of the present study was to evaluate whether affective ToM abilities are impaired in PD using multiple stimulus modalities and whether they are related to disease duration and cognitive/emotional abilities. Twenty mid-stage, non-demented people with PD and 20 matched controls were evaluated by means of two tasks requiring subjects to infer others' mental states from the eyes' expression - the Reading the Mind in the Eyes (RME) test, and from the emotional prosody - a modified version of the Reading the Mind in the Voice (RMV) test. In people with PD, cognitive function and emotional processes were assessed through cognitive tasks and batteries of facial and prosodic emotion recognition tests. Compared to controls, the PD group showed significantly impaired performances in both RME and RMV tests (p<0.0001). Affective ToM abilities in people with PD were not correlated with cognitive function or disease duration. Visual recognition of anger and auditory recognition of fear were positively correlated with RME (p=0.0028) and RMV (p<0.0001) test scores, respectively. Cross-modal impairment of affective ToM abilities is a non-motor feature of PD, unrelated to disease stage or cognitive status. A dysfunctional amygdala-centred network might represent the shared bases for impairments in fear and anger recognition and affective ToM abilities in PD.

Dementia Friendly Buildings—Approach on Architectures

Dementia’s escalating incidence, coupled with its economic burden, highlights the need for architectural designs and forms that benefit people living with dementia. This research explores strategies and design principles that focus on establishing supportive spaces for the prolonged autonomy, well-being, and safety of dementia patients. Contemporary research emphasizes the implementation of effective navigational techniques, via visual cues, familiar landmarks, and simplified layouts. For greater navigational signage, the intentional use of contrasting colors, textures, and lighting are recommended to demarcate functional areas within a structure. Incorporating familiar objects in personalized areas enhances treatment outcomes, e.g., reminiscence therapy leverages familiar objects, environmental cues, scents, sounds, and tactile features to trigger and retain memory. Integrating safety precautions such as slip-resistant flooring, handrails, and accessible bathrooms helps mitigate falls for the cognitively impaired. From a therapeutic perspective, this study draws attention towards incorporating gardens and outdoor spaces, which offers sensory stimulation, encourages physical activity, and fosters social engagement. Additionally, the integration of scents, sounds, and tactile features enriches the sensory experience for individuals with dementia. Through comprehensive consideration of design elements, this research highlights how intentionally crafted, dementia-friendly environments can convert spaces into empowering therapeutic settings tailored to address the unique need of this vulnerable group. This architectural approach acts as a valuable complement to the medical and therapeutic interventions in the treatment and care of people living with dementia and their families.

Neural cue reactivity and intrinsic functional connectivity in individuals with alcohol use disorder following treatment with topiramate or naltrexone.

Both topiramate and naltrexone have been shown to affect neural alcohol cue reactivity in alcohol use disorder (AUD). However, their comparative effects on alcohol cue reactivity are unknown. Moreover, while naltrexone has been found to normalize hyperactive localized network connectivity implicated in AUD, no studies have examined the effect of topiramate on intrinsic functional connectivity or compared functional connectivity between these two widely used medications. This study compared topiramate versus naltrexone on alcohol cue-elicited brain activation and intrinsic functional connectivity in patients with alcohol use disorder. Forty-seven participants with alcohol use disorder received daily topiramate (titrating the dose up to 200mg/day n = 21) or naltrexone (50mg/day, n = 26) for at least 6 weeks. Using functional magnetic resonance imaging (fMRI), we examined intrinsic functional connectivity during rest and alcohol cue-elicited neural activation during a visual alcohol cue reactivity task 120min following treatment administration. Functional connectivity and alcohol cue reactivity and percentage of heavy drinking days (% HDD) associations were assessed. No differences in either intrinsic functional connectivity or alcohol cue-elicited neural activity were seen between topiramate and naltrexone-treated groups. Overall, participants showed increased alcohol cue-elicited activation in three clusters spanning occipital regions involved in visual recognition of stimuli, and hypoactivation to both alcohol and control cues in three clusters involved in salience attribution and processing of emotional valence of external stimuli. No differences between topiramate versus naltrexone were observed for either functional measure or associations with post-scan % HDD. Topiramate and naltrexone enacted comparable alcohol cue reactivity and intrinsic functional connectivity patterns. Some overall responses of increased brain activation to alcohol cues in visual processing regions coupled with reduced activation to alcohol and control cues were evidenced for both treatments. These activation patterns were in regions expected to show attenuation of brain activity resulting from treatment. Topiramate and naltrexone may thus enact functional effects through similar modulation of functional neural activity in individuals with AUD.

Evaluation of repellent effects of plant‐based essential oils, red dye, and kaolin on Asian citrus psyllid

AbstractThe Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Psyllidae), vector of the pathogen causing Huanglongbing disease, is currently the most devastating pest of citrus. Despite intensive control efforts, the disease continues to spread. Diaphorina citri typically relies on tactile, visual, and odor cues for host selection. By combining an irritant (kaolin clay), a visual masking (red or blue dye), and true odor repellents, we aim to repel D. citri from citrus trees. In laboratory conditions, we conducted closed‐cage bioassays to compare D. citri response to the following treatment combinations: (1) kaolin + food colorants (blue or red); (2) kaolin + odor repellents (thyme, lavender, fir, and coriander oil), and (3) kaolin + red food colorant + thyme oil. The red kaolin treatment exerted a greater deterrent effect on D. citri adults than the blue and uncolored kaolin treatments. We also observed an additive effect in terms of D. citri repellency with the combination of thyme oil and kaolin and, to a lesser extent, coriander oil and kaolin. However, the combination of lavender or fir oils and kaolin did not increase repellency against ACP as compared with kaolin alone. Thyme oil + red kaolin oil combinations induced similar ACP repellency to that of thyme oil + uncolored kaolin. Finally, fecundity was significantly reduced by the kaolin‐based treatments compared to the thyme oil treatment and control plants. Our findings suggested the possible use of red kaolin or the combination of thyme and kaolin as a means of reducing D. citri infestation in citrus.

Multimodal language processing in school-aged Mandarin-speaking children: the role of beat gesture in enhancing memory for discourse information

Abstract Communication is typically multimodal, meaning that communication involves the utilization of various cues from different modalities. While spoken words in the auditory modality primarily convey semantic information, gestures from the visual modality complement and enhance the communication process. However, the role of visual cues, specifically beat gestures, a type of non-verbal co-speech gesture used to emphasize certain information, in language processing remains largely underexplored. The present study, using a memory task where 90 Mandarin-speaking schoolchildren aged 6–9 viewed stories individually and were later asked about what happened in the stories, investigates the role of beat gestures in enhancing the memory for discourse information in Mandarin. The results show that words with beat gestures were generally recalled better for children of all grades, indicating that by age 6, Mandarin children have already acquired the ability to utilize beat gestures to encode a discourse. This study contributes significantly to our limited understanding of the significance of visual cues in multimodal language processing.

Fast updating feedback from piriform cortex to the olfactory bulb relays multimodal identity and reward contingency signals during rule-reversal

While animals readily adjust their behavior to adapt to relevant changes in the environment, the neural pathways enabling these changes remain largely unknown. Here, using multiphoton imaging, we investigate whether feedback from the piriform cortex to the olfactory bulb supports such behavioral flexibility. To this end, we engage head-fixed male mice in a multimodal rule-reversal task guided by olfactory and auditory cues. Both odor and, surprisingly, the sound cues trigger responses in the cortical bulbar feedback axons which precede the behavioral report. Responses to the same sensory cue are strongly modulated upon changes in stimulus-reward contingency (rule-reversals). The re-shaping of individual bouton responses occurs within seconds of the rule-reversal events and is correlated with changes in behavior. Optogenetic perturbation of cortical feedback within the bulb disrupts the behavioral performance. Our results indicate that the piriform-to-olfactory bulb feedback axons carry stimulus identity and reward contingency signals which are rapidly re-formatted according to changes in the behavioral context.

Linking the lack of tactile sensory cues to consumers’ emotions in e-commerce clothing purchases: a cross-cultural study

This paper explores consumers’ emotions related to a lack of tactile sensory experiences during e-commerce clothing purchases in a cross-cultural study between South Africa and the United Arab Emirates (UAE). Data was collected from a structured, self-administered electronic questionnaire. Respondents were provided with pictures of clothing garments from which their need for touch (NFT) and emotional responses were predominantly determined. The UAE respondents tend to display generally higher levels of NFT than South Africans, with higher levels of instrumental NFT found in UAE respondents. South Africans displayed a higher emotional response than UAE respondents. The international gap in existing research regarding a lack of tactile sensory cues in e-commerce clothing purchases is addressed in this study as it highlights the importance of NFT in e-commerce clothing purchases, and the effect thereof across cultural boundaries, providing insight into the effect of tactile sensory cues on consumers’ emotions, which directly affects their purchase intention.

Citrus Yellow Vein Clearing Virus Infection in Lemon Influences Host Preference of the Citrus Whitefly by Affecting the Host Metabolite Composition.

Plant viruses have been known to alter host metabolites that influence the attraction of insect vectors. Our study investigated whether Citrus yellow vein clearing virus (CYVCV) infection influences vector attractiveness, focusing on the citrus whitefly, Dialeurodes citri (Ashmead). Free choice assays showed that citrus whiteflies exhibited a preference for settling on CYVCV-infected lemon plants versus healthy control plants. Using chromatography techniques, we found that the levels of sugars were similar in leaves and stems of both plant groups, while the contents of several amino acids in leaf or stem samples and non-volatile phenolic compounds in the leaf samples of CYVCV-infected and healthy plants differ drastically. In addition, volatile terpenes/terpenoids decreased significantly in virus-infected plants compared to healthy controls. Several of the identified volatile compounds such as α-phellandrene, α-terpinolene, p-cymene, linalool, and citral are known for their whitefly repellent properties. Further Y-tube olfactometer bioassays revealed that emissions of volatile organic compounds (VOCs) from infected plants attracted more citrus whiteflies, but not alate spirea aphids, Aphis spiraecola Patch, than those from healthy plants, suggesting that the VOCs released from CYVCV-infected lemon plants may specifically affect citrus whiteflies. Therefore, we suggest that, in addition to the visual cue of yellow vein symptoms, the preference of citrus whiteflies that settled on CYVCV-infected lemon plants was attributed to a reduction in the levels of repellent volatile compounds.

Brain connectivity for constructing new face representations in typical adults versus a prosopagnosic patient.

Will our brains get to know a new face better if we look at its external features first? Here we offer neurophysiological evidence of the relevance of external versus internal facial features for constructing new face representations, by contrasting successful face processing with a prototypical case of face agnosia. A woman with acquired prosopagnosia (E.C.) and 14 age-matched typical participants (7 women) were exposed to a face-feature matching task. External (E), internal (I) features, and whole target faces of unknown individuals (from an IdentiKit gallery) were displayed according to two different sequences: E →I→whole faces, or I→E→whole faces. Then, we studied the induced EEG activity using 'isolated effective coherence' to analyse the intracortical causal information flow among face-sensitive nodes. Initial presentation of external features (E before I), when compared to internal ones, triggered connections encompassing extensively the right-hemisphere face processing pathway [from posterior visual cortices for initial structural analysis, towards both intermediate (occipitotemporal) and high-level (prefrontal) relay stations], in which face-identity is thought to emerge progressively. Also, whereas exposure to internal features as second stimulus seemed to demand some sort of basic visual processing, external features triggered again more widespread and integrative connections. Connections for whole faces closing the E-I sequence resembled those for external features initiating the same sequence. Meanwhile, the predominant connections for whole faces completing the I-E sequence were more restricted to specific brain areas, with relevant prefrontal activity and a few connected nodes in right posterior regions, suggesting high attentional load plus initial and intermediate processing of face identity. Interestingly, the pattern of connections that distinguished typical participants from E.C. in the I-E sequence was the recruitment of left posterior visual regions, presumably underlying analytical subroutines for structural encoding of facial stimuli. These findings support that initial exposure to external features, followed by internal ones, provides the best visual cue to acquire new face configurations. Nevertheless, in case of face agnosia after right posterior damage, relying preferentially on internal features and left hemisphere specialized subroutines might be an alternative for cognitive training.

Integrating vestibular and visual cues for verticality perception.

Verticality is the perception of what's upright relative to gravity. The vestibular system provides information about the head's orientation relative to gravity, while visual cues influence the perception of external objects' alignment with the vertical. According to Bayesian integration, the perception of verticality depends on the relative reliability of visual and vestibular cues. Ambiguities in vestibular signals are resolved through visual information, with the brain integrating these cues alongside prior knowledge of the upright orientation. While it is established that both vestibular and visual cues contribute to verticality perception, the precise mechanisms underlying this integration remain unclear. Here we investigated how the human brain combines vestibular and visual cues to perceive verticality based on their reliability. We assessed verticality perception using a signal detection theory based visual verticality detection task. Participants were shown lines that were either vertical or tilted and asked to judge their orientation. To manipulate cue reliability, we used optokinetic stimulation for visual cues, galvanic vestibular stimulation for vestibular cues, and a combined visual-vestibular condition by simultaneously delivering optokinetic and galvanic vestibular stimulation. Sham stimulations were administered to control for non-specific effects. Our findings demonstrate that reductions in the reliability of visual and vestibular cues impair sensitivity to verticality, with visual cues exerting a more pronounced influence. Importantly, no changes in response bias were observed. The observed pattern aligns with a model in which the relative contributions of visual and vestibular inputs are determined by linear weightings and their combined summation.

Enhancing navigation performance in unknown environments using spiking neural networks and reinforcement learning with asymptotic gradient method

Achieving accurate and generalized autonomous navigation in unknown environments poses a significant challenge in robotics and artificial intelligence. Animals exhibits superlative navigation capabilities by combining the representation of internal neurals and sensory cues of self-motion and external information. This paper proposes a brain-inspired navigation method based upon the spiking neural networks (SNN) and reinforcement learning, integrated with a lidar system that serves as the local environment explorer, by which realizes high performance of obstacle avoidance and target arrival in mapless circumstances. An asymptotic gradient method is introduced to optimize the backpropagation during training, which facilitates the improvement of model robustness. The results of our experiments conducted on the Gazebo platform showcase how our approach effectively improves navigation performance in various intricate environments. Our approach yielded a higher success navigation rate ranging from 2% to 5%, depending on the SNN timesteps. Considering the inherent lower computational cost of SNN, this work contributes to advancing the fusion of SNN and reinforcement learning techniques for energy-efficient autonomous navigation tasks in real-world mapless scenarios.

Coming home: how visually navigating ants (Myrmecia spp.) pinpoint their nest.

Visually navigating Myrmecia foragers approach their nest from distances up to 25 m along well-directed paths, even from locations they have never been before ( Narendra et al., 2013). However, close to the nest, they often spend some time pinpointing the nest entrance, sometimes missing it by centimetres. Here, I investigated what guides homing ants in their attempt to pinpoint the nest entrance. As the ants approach the nest, their behaviour changes. At approximately 1 m from the nest, the ants slow down, their scanning amplitude becomes larger and their path direction changes more frequently. This change in scanning behaviour is not triggered by local olfactory, tactile or visual cues because ants tethered on a trackball 30-50 cm above ground also exhibit it at 0.6 m compared with 1.6 m distance from the nest. Moreover, the ants are able to pinpoint the nest when such local cues are removed by covering the ground around the nest or the nest entrance itself. Myrmecia ants thus rely on information from the global panorama when pinpointing the nest. During learning walks, these ants appear to systematically collect views directed toward and away from the nest ( Jayatilaka et al., 2018). Homing ants indeed change gaze and body axis direction appropriately with a delay when encountering views to the left or to the right of the nest. However, image analysis shows that close to the nest, opponent views with the same orientation become too similar, explaining the growing uncertainty reflected in the ants' increased scanning behaviour during homing.

Enhancing the Trapping of Melon Fruit Fly, Zeugodacus cucurbitae Coquilette through Synergizing the Odour and Visual Cues

The melon fruit fly (Zeugodacus cucurbitae Coquillett) poses a significant threat to cucurbit crops with substantial yield losses and challenging sustainable vegetable production. This study systematically investigated efficient color-based visual cues for attracting melon flies and explored the synergistic effects of these visual cues in conjunction with odour cues. This study was conducted in Agricultural College and Research Institute, TNAU, Madurai during 2024. Our studies included investigations on preferred colour by melon fly through olfactometer &amp; insect cage bioassays in no choice &amp; multiple choice conditions. The additive effect of the preferred colour when combined with the fruit fly attractive odour cue was investigated under field conditions. For both male and female melon fruit flies, yellow colour (RBG coordinates - 255:255:0) consistently emerged as the most efficient visual cue followed by white (255:255:255) and red (255:0:0). Field trials also confirmed the attractiveness of yellow colour as it outperformed other colours. The visual cue, yellow colour and odour cue (synthetic blend of four fruit fly EAG active synthetic compounds in a known ratio) were combined and found to be synergistic as this fusing captured significantly more flies than the either cues alone. These results highlighted the yellow colour as the most attractive visual cue for melon flies and combining effective of visual cues with established odour attractant to greatly enhance the trapping efficiency. This integrated approach offers a promising strategy for the management of melon fly and reduction of reliance on chemical pesticides contributing to more sustainable pest control in cucurbit production. The findings have significant implications for pest management strategies, especially in regions facing melon fly infestations that threaten crop yields and export potential.

Investigating the impacts of auditory and visual feedback in advanced driver assistance systems: a pilot study on driver behavior and emotional response

In the autonomous vehicle industry, Advanced Driver Assistance Systems (ADAS) are recognized for their capacity to enhance service quality, improve on-road safety, and increase driver comfort. Driver Assistance Systems are able to provide multi-modal feedback including auditory cues, visual cues, vibrotactile cues and so on. The study will concentrate on assessing the impacts of auditory and visual feedback from assistive driving systems on drivers. A group consisting of five participants (N = 5) was recruited to take part in two sets of driving experiments. During the experimental sessions, they were exposed to several reminders designed for drivers in audio-only format and audio-visual format, respectively. Their driving behaviors and performances were under researcher’s observation, while their emotions were evaluated by YOLO v5 detecting model. The results reveal that the participants higher compliance rate and strong emotional reactions (especially the feelings of anger, sadness and surprise) towards the unimodal feedback of audio-only driving reminders. There is no strong evidence showing that the bimodal ADAS feedback of audio-visual cues effectively improve drivers’ performance during driving period. However, both the emotion data and user satisfaction results indicate that participants experienced an increase in feelings of happiness when they were able to visualize the AI assistant while hearing the audio reminders from the assistant. The study serves as one of the pioneering studies aimed at enhancing the theoretical foundation in the field of automotive user interface design, particularly concerning the design of auditory functions.

Chemical signatures of social information in Barbary macaques

Primates are well-known for their complex social lives and intricate social relationships, which requires them to obtain and update social knowledge about conspecifics. The sense of smell may provide access to social information that is unavailable in other sensory domains or enhance the precision and reliability of other sensory cues. However, the cognition of social information in catarrhine primates has been studied primarily in the visual and auditory domain. We assessed the social information content of body odor in a catarrhine primate, the Barbary macaque (Macaca sylvanus), in three semi-free ranging groups at Affenberg Salem, Germany. In particular, we related socially relevant attributes (identity, genetic relatedness, rank, sex, age, group membership) to chemical profiles of body odor. We applied non-invasive active sampling via thermal desorption tubes and analyzed samples by gas chromatography–mass spectrometry. We found robust evidence for individual odor signatures and limited support for kin signatures. Chemical profiles were also related to group membership, but little to rank, sex or age. The detected associations between chemical profiles and socially relevant attributes form the theoretical foundations for olfactory information transfer, highlighting the potential of body odor to provide valuable social information in this highly visually oriented primate.

Do goats recognise humans cross-modally?

Recognition plays a key role in the social lives of gregarious species, enabling animals to distinguish among social partners and tailor their behaviour accordingly. As domesticated animals regularly interact with humans, as well as members of their own species, we might expect mechanisms used to discriminate between conspecifics to also apply to humans. Given that goats can combine visual and vocal cues to recognise one another, we investigated whether this cross-modal recognition extends to discriminating among familiar humans. We presented 26 goats (17 males and nine females) with facial photographs of familiar people and two repeated playbacks of a voice, either congruent (from the same person) or incongruent with that photograph (from a different person). When cues were incongruent, violating their expectations, we expected goats to show changes in physiological parameters and moreover, respond faster and for longer after playbacks. Accordingly, heart rate decreased as the playback sequence progressed, but only when the face and voice presented were incongruent. Heart rate variability was also affected by congruency, but we were unable to determine precisely where differences lay. However, goats showed no changes in time taken to respond, or how long they responded for (our primary variables of interest). We also found evidence to suggest that shifts in cardiac responses may not have been robust. Although our findings could imply that goats had successfully perceived differences in congruency between the visual and vocal identity information presented, further evidence is needed to determine whether they are capable of cross-modal recognition of humans.

Modulation by NPY/NPF-like receptor underlies experience-dependent, sexually dimorphic learning

The evolutionary paths taken by each sex within a given species sometimes diverge, resulting in behavioral differences. Given their distinct needs, the mechanism by which each sex learns from a shared experience is still an open question. Here, we reveal sexual dimorphism in learning: C. elegans males do not learn to avoid the pathogenic bacteria PA14 as efficiently and rapidly as hermaphrodites. Notably, neuronal activity following pathogen exposure was dimorphic: hermaphrodites generate robust representations, while males, in line with their behavior, exhibit contrasting representations. Transcriptomic and behavioral analysis revealed that the neuropeptide receptor npr-5, an ortholog of the mammalian NPY/NPF-like receptor, regulates male learning by modulating neuronal activity. Furthermore, we show the dependency of the males’ decision-making on their sexual status and demonstrate the role of npr-5 as a modulator of incoming sensory cues. Taken together, these findings illustrate how neuromodulators drive sex-specific behavioral plasticity in response to a shared experience.

Promoting health behavioral intention through short videos: roles of audiovisual cross-modal correspondence in health communication

PurposeHealth short videos are serving as a powerful tool for encouraging individuals to actively adopt healthier behaviors. The sensory cues applied in these videos can be useful for engaging peripheral processing and enhancing attitudes. While previous research has examined the effects of various single cues, this study features a pioneering attempt to explore the roles of audiovisual cross-modal correspondence, encompassing multisensory cues perceived through different modalities, in health communication.Design/methodology/approachA 2 (color: warm/cool) × 2 (music tempo: fast/slow) between-subjects experiment was conducted to observe 120 participants’ responses to a health short video promoting eye health that was created using four different combinations of background color and background music tempo.FindingsIt was found that the congruent color–tempo pairings, that is blue &amp; slow and orange &amp; fast, led to more positive attitudes toward the videos than the incongruent pairings, that is blue &amp; fast and orange &amp; slow. The effect of cross-modal correspondence on attitude was fully mediated by processing fluency, with gender acting as a moderator between the two variables. Furthermore, individuals’ attitudes toward a short video positively influenced their health behavioral intentions.Originality/valueThese findings not only lend support to the theoretical framework of “multisensory cues-fluency-attitude-intention” chain for persuasion purposes but also have practical implications for creating effective health short videos.

Visual Reliance in Severe Hearing Loss: Visual Evoked Potentials (VEPs) Study.

Whether to rely on the visual cues in cases with severe hearing loss with adequate amplification is a matter of debate. So, this study aims to study visual evoked potentials (VEPs) in children with severe or profound HL, whether fitted with HAs or CIs. This study included three groups of children matched in age and gender: normal hearing, children with hearing thresholds >70 dBHL and fitted with power HAs, and children fitted with CIs. All cases were subjected to pure tone audiometry (aided and unaided), speech discrimination scores, ophthalmic examinations, and visual evoked potentials (VEPs). SD% scores significantly improved with the use of VCs in both CI and HL groups, and a significantly higher P100 amplitude of VEPs in both CI and HL groups (more in children fitted with CIs). Cross-modal reorganization in severe degrees of HL is of great benefit whether they are fitted with HAs or CIs.

Brainsourcing for temporal visual attention estimation

AbstractThe concept of temporal visual attention in dynamic contents, such as videos, has been much less studied than its spatial counterpart, i.e., visual salience. Yet, temporal visual attention is useful for many downstream tasks, such as video compression and summarisation, or monitoring users’ engagement with visual information. Previous work has considered quantifying a temporal salience score from spatio-temporal user agreements from gaze data. Instead of gaze-based or content-based approaches, we explore to what extent only brain signals can reveal temporal visual attention. We propose methods for (1) computing a temporal visual salience score from salience maps of video frames; (2) quantifying the temporal brain salience score as a cognitive consistency score from the brain signals from multiple observers; and (3) assessing the correlation between both temporal salience scores, and computing its relevance. Two public EEG datasets (DEAP and MAHNOB) are used for experimental validation. Relevant correlations between temporal visual attention and EEG-based inter-subject consistency were found, as compared with a random baseline. In particular, effect sizes, measured with Cohen’s d, ranged from very small to large in one dataset, and from medium to very large in another dataset. Brain consistency among subjects watching videos unveils temporal visual attention cues. This has relevant practical implications for analysing attention for visual design in human-computer interaction, in the medical domain, and in brain-computer interfaces at large.
